What Owners Say
""Problems started in October 2024. The truck would sometimes not start. I tried the easy fixes-replacing the battery, it was5 years old anyway, replacing the fuel filter and spark plug cables but it continued to have trouble starting. I finally had it towed to a local independent shop. It initially started for them but they kept it a while to duplicate the problem and finally determined the fuel pump needed to be replaces. It cost $1000.""
